Constructor & Destructor Documentation

Base_Int128()

omw::Base_Int128::Base_Int128

(

int64_t

value

)

Uses omw::Base_Int128::sets(int64_t) to initialize.

Member Function Documentation

operator bool()

omw::Base_Int128::operator bool ( ) const

inlineexplicit

If the value is 0, false is returned. true for any other value.

operator<<=()

omw::Base_Int128 & omw::Base_Int128::operator<<=

(

unsigned int

count

)

See Bitwise Shift Operators in Language Support.

sets() [1/2]

void omw::Base_Int128::sets	(	const uint8_t *	data,
		size_t	count
	)

Parameters

data	Pointer to a big endian byte buffer
count	Number of bytes to read

Interprets the value from a byte buffer as signed: The sign bit (MSB of data[0]) is extended.

If data or count is 0, the object remains unchanged.

Exceptions

• std::overflow_error if count is greater than 16

sets() [2/2]

void omw::Base_Int128::sets

(

int64_t

value

)

Extends the sign bit.

setu() [1/2]

void omw::Base_Int128::setu	(	const uint8_t *	data,
		size_t	count
	)

Parameters

data	Pointer to a big endian byte buffer
count	Number of bytes to read

Interprets the value from a byte buffer as unsigned.

If data or count is 0, the object remains unchanged.

Exceptions

• std::overflow_error if count is greater than 16

setu() [2/2]

void omw::Base_Int128::setu

(

uint64_t

value

)

Does not extend the sign bit.
